How can I select all the keyframe for an object or many objects?
I believe I found a close answer. Since Google was no help, I click on all the buttons. I found butted that looks like mouse pointer on dope sheet bar and it is called "Only incude channels relating to selected objects" and if you click that you will only see keyframe for selected object or objects. So if you select object first then click button you can then select all and only get the keyframe for selected object or objects. If no one post a better answer in couple days I will select this as the answer.
